Solid build quality
The red PCB looks nice and the components seem well-soldered. One unit had a slightly noisy output, but the other five worked perfectly.

Easy to integrate
Setup took less than 10 minutes. The pinout is standard, making it compatible with most breadboards and microcontrollers I own.

Perfect for my aquarium project
This sensor works flawlessly for monitoring water levels in my custom aquarium setup. The analog output is stable and easy to read with an Arduino.

Reliable air pressure detection
Integrated this into my HVAC monitoring system. It responds quickly to changes in air pressure and has been running for months without issues.

Good value for altitude sensing
Used this for a small weather balloon project. It's accurate enough for hobbyist use, though calibration is required for precise readings.
Q: Is the 5V input safe for long-term use?
A: Yes, the module includes a voltage regulator and can safely operate at 5V continuously within the specified temperature range.
Q: Is this sensor waterproof for submersion?
A: The sensor module itself is not fully waterproof for deep submersion. It is designed to measure water level via air pressure in a tube or detect surface contact. Please protect the electronics from direct water exposure.
Q: Does this come with a library for Arduino?
A: We do not provide a proprietary library, but this sensor works with standard analog read functions. Many community-created libraries for generic pressure sensors are compatible.
Q: Can this measure negative pressure (vacuum)?
A: No, this specific model is designed for gauge pressure ranging from 0 to positive values. It is not suitable for measuring vacuum or negative pressure.
Q: What is the maximum cable length recommended?
A: For optimal signal integrity, we recommend keeping the connection cables under 1 meter. Longer cables may introduce noise to the analog signal.
